Linear two-point scaling only. It does not linearize nonlinear sensors (RTD, thermocouple, square-root flow) and does not replace a documented loop calibration.
Formula & guidance
EU = EU_low + (reading − sig_low) ÷ (sig_high − sig_low) × (EU_high − EU_low)

Change the example inputs and check each field’s units. Use equipment datasheets and applicable project standards for final decisions. Results do not establish Canadian electrical-code compliance or certify a design.
